RUI: COLLABORATIVE RESEARCH: Tectonic Setting and Emplacement Models for Sheet-Like Plutons, North Cascades Washington

在许多挤压造山带中，嵌块板状或片状岩体是常见的，但它们的构造意义或侵位机制尚不清楚。北喀斯喀特（白垩纪海岸深部杂岩的一部分）的结晶岩心以片状岩体及其变形围岩为主。本项目将评估这些岩体的侵位与区域构造之间的关系，以了解岩浆活动与侵位机制之间的联系。结果应适用于若干造山带，其中片状岩体也是造山带的重要组成部分。

In a number of compressional orogens clognate tabular or sheet-like plutons are common, yet their tectonic significance or mechanism of emplacement is not well understood. The crystalline core of the North Cascades (part of the Cretaceous Coast Plutonic Complex) are dominated by sheet-like plutons and their deformed wall rocks. This project will evaluate the relationship between emplacement of these bodies and the regional tectonics in order to understand the links between magmatism and emplacement mechanisms. Results should be applicable to several orogens in which sheet-like plutons also are an important part.
